Photoshop - How do you "edit mask" & save to &

ricwhite · Post by **ricwhite** » Fri Jul 16, 2004 2:15 pm

I am making the ground .tif for a Halo level. I don't know how to isolate the grass area by "editing the mask" and then saving it to the "alpha channel." I know how to do that in Paint Shop, but not Photoshop

Any help would be appreciated.

Thanks

you go to the channels tab and click the "create alpha channel" button and draw onto that.

so i guess u dont need to save it or anything? i guess it will just save when u save the whole image...

but yea some other advice is to go screw with the files for the tutorial level that are provided. i think that theres a ton of psd files somewhere...
